Method Details

checkEmbeddedNulls

public static RubyString checkEmbeddedNulls(ThreadContext context,
 IRubyObject obj)

Check to see if the supplied object (which is convertable to a string) contains any null (\0) bytes. It will throw an ArgumentError if so and a TypeError is obj is not a string{able}.

Parameters:

context - the current thread context

obj - object to be made into a string and checked for NULLs

Returns:

the converted str (or original if no conversion happened).

checkID

public static RubySymbol checkID(ThreadContext context,
 IRubyObject obj)

Convert the supplied object into an internal identifier String. Basically, symbols are stored internally as raw bytes from whatever encoding they were originally sourced from. When methods are stored they must also get stored in this same raw fashion so that if we use symbols to look up methods or make symbols from these method names they will match up. For 2.2 compatibility, we also force all incoming identifiers to get anchored as hard-referenced symbols.
